Open Ocean Specimens
Three remarkable secret fish species exist without geographic restrictions, potentially appearing throughout any ocean location within the Second Sea. This mechanic significantly expands fishing opportunities for players seeking these particular creatures, as any water-based location becomes a potential encounter zone.
The Doge Fin and Toilet Fish
The Doge Fin and Toilet Fish share several characteristics that distinguish them from location-specific secret species. Both creatures possess a 65% progress bar, indicating relatively manageable reeling mechanics compared to higher-difficulty specimens. Mist worms function as the preferred bait for both species, offering a potential efficiency gain for players hunting both creatures simultaneously. The Doge Fin presents a catch rate of 1 in 2,439, while the Toilet Fish offers a slightly improved probability of 1 in 2,726, making these open ocean species viable targets for extended fishing sessions.
The Frog Fish
The Frog Fish completes the trio of unrestricted secret species with a 92% progress bar and a catch probability of 1 in 2,941. Unlike its open ocean companions, the Frog Fish demands luminous larvae as bait rather than mist worms. The high progress bar percentage suggests that successful capture requires substantial player skill during the tension phases of encounters, making this species a rewarding achievement for dedicated anglers.
Bait Strategy and Resource Management
The bifurcation of bait preferences among Second Sea secret fish creates strategic decisions for players planning comprehensive hunting expeditions. Luminous larvae serve as the preferred bait for approximately half of the secret species, including the Verdant Mirage, Abyssal Monstrosity, Phantom Koi, Molten Ripple, Thorn Fish, Primordial Levi, and Frog Fish. Golden worms remain essential for the Storm Skipper, while mist worms facilitate encounters with the Doge Fin and Toilet Fish.
Resource management becomes paramount during extended secret fish hunting campaigns. Players should prioritize accumulating substantial bait reserves before initiating serious collection efforts. The unpredictable nature of secret fish spawning means that adequate bait supplies prevent frustrating situations where resource depletion interrupts promising fishing sessions. Strategic farming of bait-producing fish or purchasing from in-game vendors ensures continuous hunting capability.
